To guarantee consistency for the read-modify-write access in
cros_ec_hwmon_cooling_set_cur_state(), locking is necessary.
The locking will use standard hwmon device locks, which requires
the hwmon device to be ready before the fan devices are set up.
Reorder the initialization so this works.

The driver has a match table for the i2c bus wired into its driver
structure, but the table is not exported with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE() entry so module alias information
is generated for automatic module loading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the driver registration structure, and the missing module alias
publication.

The GXCAS GXHT30 is a humidity and temperature sensor that is a
drop-in replacement for and fully software compatible with the
Sensirion SHT30.
It is handled by the "sensirion,sht30" fallback compatible without
any driver changes; manual instantiation works with the existing
sht3x device name. Document the chip as supported.

Add an of_device_id table to support devicetree based instantiation
of the supported sensors.
The devicetree binding models all higher accuracy parts with a
fallback to the base part of their group, so only the two base
compatibles need to be listed. The match data distinguishes the
humidity and temperature parts (SHT3x) from the temperature-only
parts (STS3x), which require different configuration.
Start enum sht3x_chips at 1: with sht3x equal to 0, the OF match
data for the SHT devices would be NULL, causing i2c_get_match_data()
to fall back to i2c_device_id name matching, which fails for
devicetree names. The devices would then only work because the
resulting chip id 0 happens to equal sht3x. Non-zero match data
avoids relying on that coincidence.

Enable T_Sensor for ROG STRIX X870E-E GAMING WIFI.
Board specs list the sensor, reading at the standard for this family
address without the thermistor connected to the motherboard, returns
-62, which is one of the known blank values (the other one in -40)
readings for temperature sensors in the ASUS EC when there is no
thermistor connected to the motherboard socket. With that evidence we
conclude that the T_Sensor can be enabled in the driver for this board.

tmp401 is missing HWMON_C_REGISTER_TZ. So a devicetree thermal
zone referencing a such sensor ('thermal-sensors = <&tmp411 N>')
fails to register it. Then its cooling-maps is not set, which means
that the fans are not managed.

Since ACPI_POWER_METER_CLASS is also used for generating ACPI netlink

The ChromeOS EC APIs use integers representing degrees kelvin for
temperatures. The default conversions from linux/units.h will then
always convert these integer degrees celsius with a 150 millidegree
offset. This is a bit confusing, as it also differs from other CrOS EC
tooling. Internally the EC uses a kelvin to celsius offset of a round
273, so the current conversion is also not entirely accurate.
Implement a custom conversion which preserves round values.

Add a driver for the temperature and voltage sensors on PolarFire SoC.
The temperature reports how hot the die is, and the voltages are the
SoC's 1.05, 1.8 and 2.5 volt rails respectively.
The hardware supports alarms in theory, but there is an erratum that
prevents clearing them once triggered, so no support is added for them.
The hardware measures voltage with 16 bits, of which 1 is a sign bit and
the remainder holds the voltage as a fixed point integer value. It's
improbable that the hardware will work if the voltages are negative, so
the driver ignores the sign bits.
There's no dt support etc here because this is the child of a simple-mfd
syscon.

Add support for ROHM BD12790 hot-swap controller which is largely
similar to Analog Devices adm1272.

15mV/30mV current-sense ranges as the ADM1272, and the same VRANGE
(bit 5) and IRANGE (bit 0) layout in PMON_CONFIG. It therefore uses
a dedicated coefficient table that mirrors adm1272_coefficients, with
the following differences derived from BD12790 datasheet Table 1 (p.18):
- power 60V/30mV: m=17560 (vs. 17561)
- power 100V/30mV: m=10536 (vs. 10535)

Populating the i2c_device_id -table is not enough to make the
driver module automatically load when device-tree node for the
power-monitor is parsed at boot.
Adding the of_device_id tables causes the driver module to be
automatically load at boot. Testing has been done with rather old Debian
system.
When inspecting the generated module-aliases with the insmod, following
entries seem to be the difference:
alias: of:N*T*Cadi,adm1075C*
alias: of:N*T*Cadi,adm1075

The NAND timing calculation assumes that command and address setup and
hold intervals T1-T4, T7 and T11 each take one controller clock. It also
uses the original A10 delay encodings for tWB, tADL, tWHR and tRHW.
The H6/H616 NDFC defines the setup and hold intervals as two internal
clock cycles and uses different delay encodings. Add the H616 timing
characteristics and select them through the controller capability data so
the clock solver and timing fields match the hardware.

The tADL and tWHR timing fields use four encoded delays, but the driver
currently derives their values with a shift. This hides the actual
controller timing characteristics and lets the clock solver select a
32-cycle delay that the fields cannot encode.
Describe the legacy 7, 15, 23 and 31 cycle thresholds explicitly and use
the tables for both clock selection and field lookup. This prepares the
driver for controllers with different encodings.

Currently, scmi_pd_set_perf_state() treats a performance state of 0 as
invalid and returns -EINVAL. As a result, devices attached to SCMI
performance domains can report failures when relinquishing their
performance vote.
The OPP framework use performance state 0 to indicate that no performance
vote is required. For example, dev_pm_opp_set_rate(dev, 0) is commonly
used (by firmware or linux) when a device is runtime suspended.
A zero performance state does not require any SCMI performance request
to be sent. Treat it as a no-op and return success instead of reporting

v4l2_async_match_notify() creates ancillary media links before adding
asc->asc_subdev_entry to sd->asc_list.
If ancillary link creation fails, the function jumps to
err_call_unbind while asc_subdev_entry has not been linked yet. Async
connections are zero-allocated, so the list entry still has NULL next
and prev pointers on this path. Calling list_del() on it can therefore
dereference NULL instead of returning the original link creation error.
Do not delete asc_subdev_entry from err_call_unbind. There is no list
insertion to undo on this path; the bound callback and sub-device
registration are the operations that need to be rolled back.

Refactor dev_fill_forward_path() to take a struct net_device_path_ctx
pointer instead of a (dev, daddr) pair, so the caller can build and
populate the context up front and keep it after the forward path walk.
This allows additional fields (e.g. vlan and ether_type) to be carried
in the context and shared with ndo_fill_forward_path implementations,
instead of being reconstructed on the stack inside the core helper.
Update the mtk_ppe_offload, airoha_ppe and nf_flow_table_path callers to
allocate and fill the context before invoking dev_fill_forward_path().
The network topology resolution behaviour is unchanged.
This is a preliminary patch to enable HW flowtable offload for IPv4
over IPv6 tunnels.

validate_and_copy_from_user() allocates a page to store data from
userspace via get_zeroed_page(), and then returns it as a buffer.
Neither the function itself nor its callers require struct page access.
This buffer can easily be allocated with kzalloc() as there is nothing
special about it that requires going through the page allocator.
kzalloc(), which internally reduces to kmalloc() with __GFP_ZERO,
provides a better API and kfree() does not need to know the size of the
freed object. Additionally it removes the casts of (void *) and
(unsigned long) which only obfuscate the code.
Replace get_zeroed_page() with kzalloc() and free_page() with kfree().

The "trigger" debugfs file has a hand-rolled ->write handler
(trigger_write()) that dereferences the per-device gpio_la_poll_priv. The
file is created with debugfs_create_file_unsafe(), and the handler never
takes a debugfs reference. Nothing keeps the object alive while the
handler runs.
priv is allocated with devm_kzalloc(). devres frees it when the platform
device is unbound. debugfs_create_file_unsafe() installs no full_proxy
wrapper, so debugfs_remove_recursive() in gpio_la_poll_remove() does not
wait for an in-flight trigger_write(). The blob_lock taken there does not
help, because trigger_write() never takes it. A write that races an unbind
therefore writes into freed memory:
trigger_write() gpio_la_poll_remove()
priv = m->private
buf = memdup_user() [may sleep]
mutex_lock(&priv->blob_lock)
debugfs_remove_recursive() [no wait]
mutex_unlock(&priv->blob_lock)
(remove returns; devres frees priv)
priv->trig_data = buf <-- use-after-free write
priv->trig_len = count
The race is reachable by root via
/sys/bus/platform/drivers/gpio-sloppy-logic-analyzer/unbind.
Create "trigger" with debugfs_create_file() instead. Its full_proxy
wrapper makes debugfs_remove_recursive() drain any in-flight ->write
before it returns.
The use-after-free is confirmed under KASAN with a minimal reproducer of
the same debugfs_create_file_unsafe() plus devm_kzalloc() pattern
(available on request); it produces a slab-use-after-free write in the
handler.

If acpi_dev_get_resources() returns overlapping I/O or memory resources,
the subsequent registration of a platform device will fail with -EBUSY
due to a resource conflict. This is reported to happen on Acer Aspire
ES1-572 [1].
Avoid that by adjusting resources returned by acpi_dev_get_resources()
to eliminate partial overlaps between them.
This has not been regarded as necessary before because putting
overlapping resources into the _CRS of one device is really pointless,
but now that the issue has been reported to actually happen in the
field, it needs to be done.
